There is no credible evidence of a 23-year-old woman giving birth to 14 children in a single delivery. Such an event would be unprecedented and extremely unlikely due to the significant health risks associated with high-order multiple births.
Historically, the largest recorded multiple birth is the case of Nadya Suleman, who gave birth to octuplets (eight babies) in 2009. All eight infants survived infancy, making it a notable case in medical history.
There are instances of young women having multiple children over several years. For example, Mariam Nabatanzi, a Ugandan woman, gave birth to 44 children by the age of 36. Her multiple births were attributed to a rare genetic condition causing hyperovulation.
